libjpeg-turbo-test: Depend on libjpegturbo. LP: #1053273.

8. By Matthias Klose on 2012-09-20

[ Tom Gall ]
* Update to stable 1.2.1. LP: #1012861.
  * Addresses CVE-2012-2806. LP: #1025537.
    A Heap-based buffer overflow was found in the way libjpeg-turbo
    decompressed certain corrupt JPEG images in which the component count
    was erroneously set to a large value. An attacker could create a
    specially-crafted JPEG image that, when opened, could cause an
    application using libpng to crash or, possibly, execute arbitrary code
    with the privileges of the user running the application.
  * Cosmetic fixes to argument lists
  * Added flags to the TurboJPEG API that allow the caller to force
    the use of either the fast or the accurate DCT/IDCT algorithms
    in the underlying codec.
  * More recent versions of autoconf add -traditional-cpp to the CPP
    flags, which causes jsimdcfg.inc.h to not preprocess correctly
    unless we expand all of the instances of the #definev macro.
  * Fixed regression caused by a bug in the 32-bit strict memory access
    code in jdmrgss2.asm (contributed by Chromium to stop valgrind from
    whining whenever the output buffer size was not evenly divisible by
    16 bytes.) On Linux/x86, this regression generated incorrect
    pixels on the right-hand side of images whose rows were not 16-byte
    aligned, whenever fancy upsampling was used. This patch also
    enables the strict memory access code on all platforms, not just
    Linux (it does no harm on other platforms) and removes a couple of
    pcmpeqb instructions that were rendered unnecessary by r835.
  * Accelerated 4:2:2 upsampling routine for ARM (improves
    performance ~20-30% when decompressing 4:2:2 JPEGs using
    fancy upsampling)
  * Eliminate the use of the MASKMOVDQU instruction, to speed
    up decompression performance by 10x on AMD Bobcat embedded
    processors (and ~5% on AMD desktop processors.)
  * add tjbench to libjpeg-turbo-test packages
  * Guard against num_components being a ridiculous
    value due to a corrupt header
  * Preserve all 128 bits of xmm6 and xmm7

[ Matthias Klose ]
* Prepare the package for quantal, basing on the 1.2.1 release tarball.
* d/patches/branch-updates.diff: Update to 20120919 of the 1.2.x branch,
  but don't bump the version to 1.2.2.
* d/patches/guard-inline-define: Remove, integrated upstream.

Strip -Wl,-Bsymbolic-functions out of LDFLAGS, so that hpcups and
pxljr can override jinit_color_converter. LP: #777670.

6. By Adam Conrad on 2012-06-20

Guard the definition of INLINE in an ifndef block, so that
third parties including our headers don't get it redefined
unexpectedly from under them (which cause the spice FTBFS)

5. By Matthias Klose on 2012-01-13

* Install jpegint.h in the -dev package.
* Install jconfig.h in the multiarch include directory.

libjpeg-turbo-progs: Remove dependency on libturbojpeg.

3. By Matthias Klose on 2011-12-20

* Sync with upstream to svn733.

* Rename libjpeg-test to libjpeg-turbo-test.
* Rename libjpeg-turbo-dbg to libjpeg-turbo8-dbg.
* Rename libjpeg8-dev to libjpeg-turbo8-dev.
* Move the docs into the -dev package, install the upstream changelog
  in the -dev only.
* Split out libturbojpeg.so into it's own package, don't let
  libjpeg-turbo8-dev depend on it.
* Fix libjpeg-turbo8-dbg package description.
* Install jconfig.h into multiarch include path.
* Remove HAVE_STD{LIB,DEF}_H from jconfig.h since they are not used and
  conflict with autoconf.
* libjpeg-turbo8:
  - Add a symbols file, with a different version for symbols only found
    in the libjpeg-turbo implementation.
  - Remove the shlibs file.
  - Breaks/Replaces libjpeg8 (<< 8c-2ubuntu5).
* Copy the exifautotran and jpegexiforient tools from the libjpeg8
  sources, install into libjpeg-turbo-progs.
* Don't install tjbench in libjpeg-turbo-progs to avoid dependency
  on libturbojpeg.
